Solid-State Electrolyte

A solid-state electrolyte (SSE) is a substance that serves as both an electron insulator and a solid ionic conductor, and it is the essential element of a solid-state battery. It can be used in electrical energy storage (EES) applications to replace liquid electrolytes, particularly those present in lithium-ion batteries. The primary benefits are complete safety, a lack of harmful organic solvent leakage concerns, low flammability, non-volatility, mechanical and thermal stability, ease of processing, low self-discharge, greater attainable power densities, and cyclability. Due to the property of lithium dendrite suppression in the presence of a solid-state electrolyte membrane, this makes it feasible, for example, to employ a lithium metal anode in a practical device without the inherent restrictions of a liquid electrolyte. The first step in creating a lighter, thinner, and more affordable rechargeable battery is to replace the conventional low capacity graphite with a high capacity anode and low reduction potential, such as lithium, which has a specific capacity of 3860 mAh g1 and a reduction potential of -3.04 V vs SHE. Furthermore, this enables energy densities in the gravimetric and volumetric range to be high enough for an electric car to go 500 miles on a single charge. Despite the potential benefits, there are still several obstacles preventing the transition of SSEs from academic research to large-scale production, with the primary one being the inferior ionic conductivity compared to that of other materials.
